meta alarm problem

[richard s]

i know this is a audio section but i am hoping some of the guys on here work in audio security shops and could help me out
i have a mk2 gti fitted with a meta alarm and just recently it has started going off about 2 mins after arming and when i turn alarm off and get in car the led flashes 3or4 times realy quick then stays lit for a while then repeats
does this relate to a certain part of the system triggering (doors/ultrasomics etc)
thanks

Bonnet switch I think or the door pins. It's been a long time since I worked on Meta alarms. Ripped mine out and put a Clifford in instead

cheers monza i think it might be fooked as it behaved for a few hours tonight but didnt today
but as it is i would rather have a alarm that keeps going off with an imobiliser that is working than turn it off
other than that do the ultrasonics have adjustable sensitivity

 I think there is an adjuster on the main brain if you can find it wind the window down and move your arm from the window into the car, it should detect you about in line with the middle of the steering wheel

i found the adjuster and just turned it down fully locked up and armed it and 2 minutes later it went off
got to work this morning and 5 mins later someone came and told me my alarm was going off
got home tonight about 5 and alarm didnt start going off till about 9.30
so i think i have either got a large animal that i cant see living in my car or the alarm is about knackered
thanks for the help monza
